Abstract:	本論文使用實驗室開發之“非異氰酸酯製程法”，製備水性PU（Polyurethane），並在化合物的選擇及合成比例上做改變，探討其中對材料性質影響的改變因素。以環氧樹脂（NPEL-128；EEW = 187）為起始物，透過二氧化碳的親核性加成反應製備環狀碳酸酯（Bis(cyclic carbonate)s）；與BDBA（1,4-butanediol bis(3-aminopropyl) ether；MW = 204.31）及Jeffamine® D-2000（MW = 2000）兩不同大小分子量胺類進行聚合反應；再經由馬來酸酐（Maleic Anhydride）的半酯化反應（Half-Esterification Reaction），以及加入適量鹼與羧酸基形成的中和反應，最後形成水性PU分散液（Aqueous-Based Polyurethane Dispersion）。分別調整起始物與胺類合成上的比例（128-Car : Amine = 1.0 : 0.9；1.0 : 1.0；1.0 : 1.1）進行反應，再以架橋劑TMPTA-AZ，與PU鏈段上的羧酸基反應形成三維交聯網狀結構，探討材料在不同合成比例下，所表現出的各項物理性質、熱性質和機械性質，之間的影響及差異性。 The present paper uses “Isocyanate-Free Process” which developed from the laboratory to prepare aqueous-based polyurethane dispersion. Besides, by changing the choice and synthesis ration of the compound, we discuss the natural influence factors of material. Using the (NPEL-128; EEW = 187) to be a start material, Bis(cyclic carbonate)s were prepared through the nucleophilic addition reaction of CO2. Then, to polymerize with two different types of molecular weight of amine, BDBA (1,4-butanediol bis(3-aminopropyl) ether; MW = 204.31) and Jeffamine® D-2000 (MW = 2000), then through the Half-Esterification Reaction of maleic anhydride, and adding the neutralization which is formed by carboxylic group with appropriate amount of base. Finally, the Aqueous-Based Polyurethane Dispersion was formed. Adjusting the synthesis ration of the start material and amine(128-Car : Amine = 1 : 0.9; 1 : 1.0; 1 : 1.1) partly, then react. After, adding the bridging reagent TMPTA-AZ into the Aqueous-Based Polyurethane Dispersion and react with the carboxylic groups of PU segment to form the three dimensional net working structure. And try to discuss the physics, thermal stability, mechanical properties of the film in a different synthesis ration of materials.
